Change the law, scientists want to resurrect the "mammoth", through the genetic modification of the elephant?

4,000 years ago, in ancient Egypt, people on that land used their wisdom at that time to create pyramids one by one.

And around the long North Pole, there are also groups of ancient creatures-mammoths, which are slowly declining.

With the rise of people, this kind of ancient creatures that make people look forward to the subjugation of the country little by little. Until now, people have only grasped them based on animal fossils.

There have been so many ancient creatures on the earth. Mammoths are basically the most well-known and most interesting ancient creatures besides Tyrannosaurus Rex. In recent years, more and more mammoth animal fossils have been excavated, and people have become more and more familiar with them. Even, because of the excellent standards of the North Pole, some ordinary but not mediocre refrigerated samples of mammoths have been unearthed. This has caused people's interests and hobbies, and also made people pay more attention: Can you see what a mammoth looks like with your own eyes?

This question seems to have an unquestionable answer when cloning technology is taking place in people's current situation. So, why did the cloned sheep and other creatures have long been available, but the biologists have been delaying and not copying the mammoth?

This needs to be from the basic principle of replication.

We know that every living being's body has its own set of genetic information. Genetic information specifically guides the growth and development of an organism, personal behavior and other aspects of daily life. In short, genetic information is equivalent to the source code of a program flow. Although you don't have this program flow, you can get this program flow by typing the code on the computer and the code-typing mobile phone software.

In this whole process, there are three key points: 1. We need to have detailed coding; 2. We need to find a "computer". If you use input, it is obvious that you cannot get this program flow; 3. To There are mobile software that type this code, because even if you have the code, but you just type on your own blog, it is unlikely to get the program flow.

The same goes for resurrecting mammoths. And the problem happens here.

First of all, we have to have a detailed "coding", that is, a detailed mammoth genetic inheritance. Unfortunately, chemicals like DNA are not very reliable and are easily destroyed in nature. At this stage, the mammoth genetics that everyone has obtained is not yet detailed. It is the first difficulty and the most crucial one. How to solve this problem? This requires the continued diligence of experts to decipher the genetic code of the mammoth.

Second, you must look for a living cell to install the mammoth's genetics. The mammoth's somatic cells have long since passed away, so it is only possible to find its relatives and friends, and it is not too "repulsive" to count on its relatives and friends. At this stage, the Asian elephant is the best candidate, so we must put the detailed genetics of the mammoth into the embryonic cells of the Asian elephant.

The third is to let Asian elephants give birth to babies and mammoth cubs. However, the genetic difference between the two organisms is 4.7? This is a relatively large number in genetics. If this problem is not addressed, miscarriage is likely to occur even if the Asian elephant mother destroys the baby mammoth. So, is there nothing biologists can do about this? maybe. With the continuing trend of artificial womb technology, it may help to create test-tube embryos of mammoths in the future.

Naturally, after talking about so many solutions, one thing must be told to everyone: this kind of plan is a drop in the bucket in terms of the difficulty of resurrecting the mammoth. Although there have been repeated news reports that we are getting closer and closer to the resurrection of the mammoth, we must understand that we are still 108,000 miles away from the resurrection of the mammoth.

Take the genetic conundrum of the first step. DNA is essentially made up of base pairs in sequence. This base pair is similar to 0 and 1 in binary on a computer. Different sequences can express different results. If mammoths are to be resurrected, biologists will have to generate the detailed DNA of the mammoths. However, at this stage of technology, the most DNA records biologists have ever generated include 580,000 base pairs. And in the genetic inheritance of mammoths, there are more than 4 billion yuan to...

Naturally, some Japanese biologists emphasized that they have already developed and designed new technologies, which can immediately obtain detailed mammoth cytoplasm (with genetic inheritance) from the refrigerated sample, and immediately transfer it to the embryonic cells of Asian elephants. However, the performance of this technology cannot be successful and is unknown.

Even if so many technical problems are solved, the hurdle in many people's hearts, or the one they can't get through, is the ethical issue. Many people think that extinct animals should be extinct, and that resurrecting them is against the law and not advisable. It's not so much to spend an already anxious scientific research budget on this technical level than to do some other scientific research. Regarding ethical issues, everyone has different opinions, but everyone should discuss more.

I believe in one thing from the beginning to the end, that is, it is better to cherish what is in front of you than to retain what is lost. The best protein kinases in mammoths are contemporary elephants. But the problem lies in that, along with people's hunting and the extrusion of living conditions, the survival of contemporary elephants also encounters great work pressure. To be exaggerated, if the mammoth has not been resurrected, the contemporary elephant needs to say goodbye.

Naturally, the technicality of resurrecting the mammoth may be a trend to be grasped. This is not only critical for everyone to protect a large number of organisms from extinction in the future, but also some people feel that the individual behavior of the mammoth is also of key practical significance for maintaining the natural environment of the Arctic Circle. However, in addition to the development trend of high-tech, don't forget to maintain the wealth of people's owners. This kind of big truth can be regarded as a major driving force for the development of human beings.
